摘要:
A cooking apparatus to improve heating efficiency and to quickly cook food. The cooking apparatus includes a heater provided at a tray receiving food to be cooked and having a pair of terminals to supply power to the heater, and a plurality of sockets provided at a rear wall of a cooking cavity. When the tray is placed on a pair of support rails of the cooking cavity and the terminals of the heater are inserted into one of the sockets, the tray is directly heated by the heater to cook the food. The heater includes a conductive film coated on a lower surface of the tray, and first and second electrodes connected to the conductive film to be opposed to each other and connected to the terminals. The conductive film and the tray are heated by current flowing through the conductive film between the first and second electrodes.

A microwave oven and a method of controlling the same that is capable of detecting the respective positions of heaters using detectors for which a number thereof is less than a number of cooking modes. Cooking is performed with the heaters in respective horizontal positions in a cooking mode in which cooking requiring the heaters to heat food is performed, while cooking is performed with the heaters positioned in the respective initial positions in a cooking mode in which the cooking not requiring the heaters to heat the food is performed. Each of the detectors is a micro switch operated by a cam. Accordingly, in the microwave oven and in the method of controlling the same, the number of the detectors to detect the respective positions of the heaters is decreased. Further, an electrical wire is connected to a single micro switch to detect the respective positions of the heaters.

A microwave oven has a food tray which can be both rotated and elevated. A weight sensing unit senses the weight of the tray and any food thereon, for controlling the operation of a tray elevation/rotation mechanism. The tray is not elevated if the weight of the food is detected to be greater than a predetermined elevation weight, in order to prevent excessive pressure from being applied to the elevation/rotation mechanism and the weight sensing unit. If the weight of the food is detected to be greater than a maximum possible cooking weight, no cooking is performed, and an error signal is displayed.

A microwave oven prevents an overcooking of small food portions. The oven includes a weight sensing device for sensing the weight of food to be cooked. If the sensed food weight is greater than a reference weight, then a cooking time is set, e.g., manually or automatically on the basis of a selected cooking mode and/or the sensed food weight. If the sensed food weight is less than the reference weight, then a maximum cooking time is automatically set which is the same, regardless of the amount by which the food weight is less than the reference weight. The cooking time cannot exceed that maximum time period, thereby ensuring that the food will not be overcooked.
